Abstract

Abstract: For quantification of the insecticide chlorantraniliprole in chilli and soil, an optimized gas chromatographic-mass spectrometric method is presented, with recoveries of 92–96%, and relative standard deviations of 1.4–2.7%. The limit of quantification is 0.01 mg/kg. Degradation of chlorantraniliprole follows first-order kinetics with half-lives between 1.6 and 1.8 days for chilli and soil. For earthworms and arthropods in the chilli field, the calculated risk quotient is found to be <1, as well as for consumers of chilli just after application of chlorantraniliprole. Residue concentrations in chilli fruit can be further reduced by 6–63% using different decontamination methods.
